DS/FH/TH混合扩频系统抗干扰性能的计算机模拟

Computer simulation of the anti—jam performance of a DS/FH/TH spread spectrum system

在扩频通信中,抗干扰性能是评价扩频通信体制优劣的重要指标。本文研究DS/FH/TH混合扩频系统的抗干扰性能,建立了系统模型及计算机模拟方案,通过计算机模拟获得了在连续波、脉冲波多音干扰、部分带宽干扰、脉冲噪声干扰情况下的系统误码率曲线,具有一定的实用价值。

In the spread spectrum communications, the jam-resistant ability is the most important. This paper studies the anti-jam performance of the DS/FH/TH hybrid spread spectrum systems, describes the system model and the simulating method. By computer simulation, we obtain the error-code performance of the system in the presence of barrage noise jamming, partial band noise jamming, pulsed niose jamming, single tone jamming and multiple-tone jamming.
